Probably going to regret saying this but, why is nearly every cosplay rated so low?

I'm not seeing why this looks bad other than it probably photoshop or some shit like that.

It's not cosplay but is photomanipulation.
Jeff uses collages of various photos, on his deviantart he has references link.

2.5 is average; most people prefer single sets over dumps because it makes more sense given the format of the site. I would personally prefer to see one or two of these posters expanded upon.
So anyway it seems 2 stars (“just below average”) makes sense for this gallery.

TBH, should not be categorized as cosplay
